Perform the installation work by pushing it on both the front and back sides of the tire.

Therefore, in the improved example 2, the weights 11a1 on the back side of the tips of the wheel chocks 11a and 11a are shown in FIG. 18C so that the tire stopper body 11 can be easily opened with respect to the handle body 12 when used. It is preferable to provide 11a1 and to form an R shape or the like so that the opposite sides of the wheel chock portions 11a and 11a in the step portion 11b4'protrude from the wheel chock portion connecting bar 11b. With this configuration, as shown in FIG. 18D, the center of gravity of the wheel chock portions 11a and 11a shifts to the front side of the handle body 12 when the wheel chock portion connecting bar 11b and the step portion 11b4'are attached to the ground. Therefore, when the tiltable handle portion 12a of the handle body 12 comes off from the handle holder 11b3, the tire stopper body 11 automatically opens with respect to the handle body 12 by the weights 11a1, 11a1 on the back side of the wheel chock portions 11a, 11a. The usability of the tire stopper 1 can be improved.
